|1 John 5:17 |
17 All unrighteousness is sin; and there is a sin that does not lead to death.4
4 John said, If any man sees his brother commit sin a sin that does not lead to death, he will ask, and God will give him life for a sin that does not lead to death. There is a sin that leads to death; I do not say that he should pray for that. 1 John 5:16
Let's analyze scripture to understand the sin that leads to death.
There are two stages in perfection [and purity] through the grace of Christ: 1st) to be raised up to the perfection of Adam and Eve in paradise, but still capable of falling to temptation, and 2nd) to be born again and raised up to union with Christ Jesus, an everlasting perfection, which is incapable of falling to sin or temptation.
The first stage of perfection occurs after you have crucified your sinful nature and received the fruit of the Spirit; here you learn to be continually watchful against temptation. After reaching this first stage of perfection, should we fall to temptation, unless we wilfully disobey, we can still choose to repent as we walk in the light and the blood of Jesus cleanses us of all sin, 1 John 1:7. However, once we have arrived at this first stage of perfection and purity, if we wilfully disobey the Lord, then we are lost; this is the sin that leads to death.
In this first stage of perfection you enter paradise and have fellowship with Christ and the Father; then you certainly have the knowledge of the truth that Heb 10:26-29 states results in no further repentance possible for wilful sins.
But this only applies after purity, after looking into the face of Jesus, and after knowledge of the truth.
In the past, after having been 'saved,' I stupidly committed some grievous sins; I asked if there was still hope for me.
His exact words to me were: "Until you look me in the face, and then return to sin, you can come back to me."
(I had not even started the journey to purity.)
To look Jesus in the face, you have to be pure: Blessed are the pure in heart, for they shall see God. Mat 5:8
This purity occurs in the first stage of perfection.
Until you are purified, (and receive knowledge of the glory of God in the face of Christ Jesus, who is the truth), and then wilfully disobey the commands of the Lord guiding you, your sins can be cleansed and forgiven.
So you still have the hope of purity. You still have changing grace available to you. You still have the chance to attain salvation.
